CHARLES J. JOHNSON, 0F DENVER, COLORADO.

DEVICE FOR PREVENTING HOLD-USPS` ON LOCOMOTIVES.

Specification of Letters Patent.

Patented Sept. '7, 1909.

Application filed April 24, 1909. Serial N o. 492,055.

To all whom it may concern:

Be it known that I, CHARLES J. JOHNSON, a subject of the King of Sweden,residing at Denver, in the county of Denver and State of Colorado, haveinvented certain new and useful Improvements in Devices for PreventingIIold-Ups on Locomotives; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This invention relates to new and useful improvements in devices forprotecting engineers and firemen upon locomotives from hold-ups andconsists in the provision of means whereby jets of steam may be directed upon persons approaching the cab from different directions, thesteam being allow-ed to escape through concealedpipes.

The invention comprises various details of construction, combinationsand arrangements of parts which will be hereinafter fully described andthen specifically defined in the appended claim.

`My invention is illustrated in the accompanying drawings, in which:-

Figure 1 is a View of the cab of an en- 4gine showing' the arrangementof steam ejecting pipes mounted therein, and Fig. 2 is an enlargeddetail View showing the arrangement of the pipesg Reference now beinghad to the details of the drawings by letters, A designates the cab ofan engine, B the boiler and C a pipe leading from the boiler andpositioned with its exit end adjacent to the rear end and directlyunderneath the roof of the cab. Said pipe C is bent upwardly as shownand provided with a suitable stop cock D within convenient reach of theengineer or fireman and theend of the pipe may be downwardly bent orflaring, as shown, and adapted to direct steam in the passageway betweenthe tender and the locomotive. A second pipe, designated by letter E,leads from the boiler, is bent downwardly at E and extends underneaththe floor of the cab and has branches F and F which lead outwardly andhave their exit ends adjacent to and directly underneath the platformintermediate the engine and tender. A suitable stop cock K is positionedin the pipe E, so as to be within convenient reach of the operator thathe may quickly have access thereto in order to allow steam to escapeforcibly.

In operation, in the event of there being an attempt to hold-up theengineer or {ireman, either one or the other may turn on the steam inthe two pipes by turning the stop cocks, thus allowing the live steam tomake exit from the boiler on both sides of the cab and also fromunderneath the roof, thus affording an efficient means by scalding theintruders and thus protecting the engineer and reman.

What I claim to be new is An apparatus for preventing hold-ups onlocomotives comprising, in combination with the boiler of an engine anda cab, pipes communicating with the boiler and leading into the cab,said pipes being bent in opposite directions, one extending downward andthence horizontally and having a flaring end.

positioned adjacent to thel entrance of the cab, theother pipe extendingunderneath the roof of the cab and having a flaring end which isdownwardly inclined, and suitable valves in said pipes. v

In testimony whereof I hereunto aiiix my signature in the presence oftwo witnesses.
